Star Wars A1U Modded Yoke - Left & Right Controls Reversed

<< < (2/2)

PL1:
The guy in the video does a really bad job describing the potentiometer tabs.
- His "up", "down", "left" and "right" tab labels are at best misleading.
- The good news is that he did correctly label the ground tabs.   ::)

There are three tabs on a pot:
- 5v / operating voltage
- Wiper (always the center tab)
- Ground

The pot acts as a voltage divider.
- The output voltage on the wiper tab depends on where the contact touches the resistive element.
- The analog encoder converts the analog voltage from the wiper tab to a digital value representing a position on that axis.

If the axis moves opposite the desired direction (i.e. right instead of left), swap the ground and 5v wires on that pot.
